Perfect Bayesian implementation

Summary We study Social Choice Sets (SCS) implementable as perfect Bayesian equilibria of some incomplete information extensive form game. We provide a necessary condition which we callcondition . The condition is analogous tocondition C that Moore and Repullo [1988] show to be necessary for subgame perfect implementation in games of complete information, and it is weaker than the Bayesian Monotonicity condition stated in Jackson [1991]. Our first theorem establishes that Incentive Compatibility, Closure and Condition are necessary for implementation.Our second theorem establishes sufficient conditions. We show that any SCS which satisfies Incentive Compatibility, Closure and a condition called Sequential Monotonicity No Veto (SMNV) is implementable. SMNV is similar in spirit but weaker than the Monotonicity No Veto condition stated in Jackson [1991]. It is also similar to a combination of condition and No Veto Power, which Abreau and Sen show to be sufficient for implementation in subgame perfect equilibrium.This paper is a revised version of a chapter of my dissertation at Stanford University, Graduate School of Business. I would like to thank, without implicating, Faruk Gul, Bob Wilson and especially John Roberts for their constant advice and encouragement. I would also like to thank participants at the 1993 Summer Meeting of the Econometric Society and a referee for comments leading to substantial improvement in the paper.

Fear and adventure tourism in Brazil

The search for new non-routine emotions and sensations has become a decisive factor in taking part in adventure tourism. As Barros and Dines (2000) have pointed out, Brazil's natural resources are abundant and have been widely used to promote the nation's tourism. Empirical literature describes fear as one of the main emotions in adventure activities, and for this reason a questionnaire was designed to examine the presence of fear before and after three adventure activities (parachuting, white-water rafting, and rock-climbing). This study not only aimed to consolidate fear as a fundamental emotion in performing such activities but also to stimulate interest for further studies in this area.     

Similarity and Competition in the Agri-Food Trade among European Mediterranean Countries

ABSTRACT

Using Eurostat and OECD data on agri-food exports, this article provides a picture of the evolution in the similarity between Italian and other European Mediterranean countries’ exports, before and after the recent financial crisis. Considering different indexes, the similarity is somewhat moderate and does not vary noticeably among the indexes when considering the EU-25 market. By contrast, a strong qualitative dissimilarity is recorded in the North American market. Overall, France and Spain appear more similar to Italy and likely to compete in the same agri-food market segments. The crisis seems associated to a slight modification of the exports structure.     

Reclaiming the ‘L’ word: Leisure Studies and UK Higher Education in neoliberal times

Leisure is a major sphere of both private and public life. It is thus of concern that the identity and profile of Leisure Studies in the Higher Education curricula of the United Kingdom have declined in prominence over the past decade. This trend is not peculiar to Leisure Studies; the social sciences as a whole are threatened by a neoliberal economic discourse which increasingly informs Higher Education strategic management. The aim of this article is to investigate the impacts of the declining status of Leisure Studies as experienced by lecturers and researchers in the subject field. It is based upon a project commissioned by the Higher Education Academy in 2015. It was found that Leisure Studies faces two principal challenges. The first is to re-establish its status as a subject field within the social sciences, the second is to ensure it retains a relevance to leisure practice, particularly in terms of the management of its provision. The article proposes greater academic engagement in ideational ‘border crossings’ to advance thinking on leisure in the social sciences and to explore opportunities for collaboration within them. We conclude that Leisure Studies arguably suffers from a crisis of representation, as opposed to a crisis of relevance.     

Reallocation of corporate resources and managerial incentives in internal capital markets

Diversified firms often trade at a discount with respect to their focused counterparts. The literature has tried to explain the apparent misallocation of resources with lobbying activities or power struggles. We show that diversification can destroy value even when resources are efficiently allocated ex post. When managers derive utility from the funds under their purview, moving funds across divisions may diminish their incentives. The ex ante reduction in managerial incentives can more than offset the increase in firm value due to the ex post efficient reallocation of funds. This effect is robust to the introduction of monetary incentives. Moreover we show that asymmetries in size and growth prospects increase the diversification discount.     

An alternative three-factor model for international markets: Evidence from the European Monetary Union

In this paper, we construct the three-factor model introduced by Chen et al. (2010) for a European sample covering 10 countries from the European Monetary Union and the period from 1990 to 2006. Two key findings result. First, we show that the properties of the European factors are comparable to those of the US factors. Second, we show that the alternative three-factor model’s explanatory power is either equal or superior to the explanatory power of traditional models when applied to five commonly known stock market anomalies. Our results thus suggest the use of international versions of the Chen et al. (2010) factor model in addition to traditional factor models in international empirical finance research.     

Supporting retailers to exploit online settings for internationalization: The different role of trust and compensation

The development of virtual technologies discloses two main opportunities for retailers, namely the possibility of complementing their offer through a multi-channel strategy in the marketplace they operate, and of extending their business in foreign countries. The online internationalization strategy requires retailers to overcome customers' privacy concern facilitating their information sharing with the firm so as to conclude the online transaction.This paper aims at helping retailers in reaching this goal by investigating the effect on behavioural information sharing in online settings of two variables emerged as relevant in literature: trust and compensation (as a form of incentive). The results of an experimental study show the key role of trust on increasing online information sharing.     

Trading imbalances,predictable reversals,and cross-stock price pressure

We test the implications of a multi-asset equilibrium model in which a finite number of risk-averse liquidity providers accommodate non-informational trading imbalances. These imbalances generate predictable reversals in stock returns. An imbalance in one stock also affects the prices of other stocks. The magnitude of the cross-stock price pressure depends on the correlations of the stocks’ underlying cash flows. The model implies that non-informational trading increases the volatility of stock returns. We confirm the model's implications using data from the Taiwan Stock Exchange.
